RS Fan Series
Developed specifically to deliver higher cooling performance at lower fan speeds, RS Molded Ring Fans also improve fuel economy.
The distinctive ringed design reduces cooling fan tip turbulence. Enclosing the fan blade circumference enhances engine cooling, and results in quieter operation. Manufactured from fiberglass-reinforced, heat-stabilized plastic materials, RS Nylon Molded Ring Fans retain their strength even at high operating temperatures.

|---|---|---|---|
| Description | With its 813 mm (32″) diameter and 8-blade layout, the RS8 is engineered for larger systems that demand high-flow performance with reduced power consumption. At approximately 4.1 kg (9.0 lb.), its fiberglass-reinforced nylon ring design offers superior structural integrity without excessive weight, while minimizing turbulence and noise for enhanced system efficiency. | The RS9 delivers high‑performance cooling with a 600 mm (23.6″) diameter and 9 blades, optimized for driving heavy cooling flow at lower fan speeds. Its molded nylon, fiberglass-reinforced ring construction enhances blade rigidity and reduces tip turbulence, resulting in quieter operation and improved fuel efficiency. Weighing around 2.5 kg (5.5 lb.), it strikes a balance between strength and lightness—ideal for trucks, buses, and agricultural or off‑highway equipment. | Designed for maximum flow and pressure at moderate fan speeds, the RS11 also features an 813 mm (32″) diameter but with 11 blades, giving it increased blade surface area for optimal cooling under high-restriction conditions. It typically weighs around 3.3 kg (7.3 lb)—a weight-efficient configuration considering its advanced blade count and ring enclosure that cut down tip turbulence and lower noise levels. |
